[PATCH 0/4] perf tools: Fix -g option handling

From: Jiri Olsa
Date: Sat Oct 26 2013 - 10:27:12 EST


hi,
changing the '-g/-G' options for record/top commands
to take NO argument and enable unwind method based
on .perfconfig setup (using FP by default).

The current -g option parsing moves into the
'--call-graph' option.

Examples:
$ cat ~/.perfconfig:
[top]
call-graph = fp

[record]
call-graph = dwarf,8192

$ perf record -g ls
- enables dwarf unwind with user stack size dump 8192 bytes

$ perf top -G
- enables frame pointer unwind

$ perf record --call-graph=fp ls
- enables frame pointer unwind

$ perf top --call-graph=dwarf,4096 ls
- enables dwarf unwind with user stack size dump 4096 bytes

thanks,
jirka
